摘　　要：2013年召开的“全国金刚石找矿勘查现场研讨会”,标志着我国新一轮原生金刚石矿找矿勘查工作的开始。近十年以来,原生金刚石矿找矿勘查实践与研究取得了一系列新进展:安徽栏杆地区和辽宁瓦房店地区新增一批原生金刚石资源量,进一步提升了我国金刚石资源保障能力;新划分出辽宁第Ⅳ金刚石成矿带和山东平邑—费县金刚石成矿带,在全国多个地区发现了新的找矿线索,进一步拓展了金刚石原生矿的找矿空间;进一步完善了构造解析-三维建模-工程验证、高分辨率遥感信息提取等综合找矿方法,形成了深部找矿和发现隐伏岩体的新思路;含矿岩体成因研究、金伯利岩(钾镁煌斑岩)侵位模型、金刚石原产地研究等取得了新认识;年代学研究表明,我国含金刚石母岩的成矿时代从古生代延伸到晚中生代,具有显著的多期次成矿特征。此外,文章根据近十年来金刚石找矿勘查与研究取得的新进展及存在的新问题,提出了今后原生金刚石找矿勘查与研究的相关建议。The“National Diamond Exploration Field Seminar”held by China Geological Survey in Suzhou,Anhui in 2013 kicked off a new round of primary diamond deposits exploration in China.In the past decade,a series of new progress in the exploration and research of primary diamond deposits have been made:the new batch of primary diamond resources identified in Langan,Anhui and Wafangdian,Liaoning further enhanced domestic supply ability of diamond resoureces.The VI diamond mineralization belt in Liaoning,the Pingyi-Feixian diamond mineralization belt in Shandong and new prospecting clues in other regions will expand the exploration spaces of primary diamond deposits.The comprehensive exploration methods such as tectonic analysis-3D modeling-engineering verification,and high-resolution remote sensing information extraction are new exploring ideas for deep exploration and the discovery of hidden rock bodies.New insights in the genesis of diamond-bearing rock bodies,the emplacement model of kimberlite(potassium magnesium lamprophyre),and the study of diamond source area have been acquired.The chronological studies have shown that the mineralization of diamond-bearing parent rock in China extends from the Paleozoic to the late Mesozoic,which embodies the feature of multi-stage metallogenesis.Based on the progress and new problems in diamond exploration and research in the past decade,the suggestions for future exploration and research of primary diamond deposits is also proposed in the paper.
